-Be it known-that I, FERDINAND. ERTS, a citizen of the United States of America, residing at Detroit, in the county of /Vayne andState of Michigan, have invented certain new and useful Improvements in Music-Record Guides, of which the 61- lowing is a specification, reference being had therein to the accompanying drawings.

In winding the records used in mechanical pianos, pianolas or the like, difficulty is foundin keeping the flexible band, which constitutes the record and is usually of paper or like material liable to injury,..

smooth and feeding it to the roll with even tension. j I

Thisinventlon relates to a record 'uide adapted for use on any instrument 0? the 1 class or type mentioned, which maintains a constant-tension on the record as it is bemg Wound.

The invention consists in the matters hereinafter setforth, and more particularly pointed out in the appended claims.

' winding roller .3, and feed roll 4, together" In the drawings, B

the like, showin the tracker board, feed roller and rewindin roll, with the'driving mechanism indicated, together with a record uide embodying features of the invention. 1g. 2 is-a view in detail of-the uide itself v Fig. 3 is a View of an adjustable earin'g.

, Referring to the drawings, 1" indicates inolosing the tracker board 2 of a casin piano a or like instrument, the record or rewith the usual roll driving spindles or journals 5, all of standard type permitting the removal, .if desired', of the record roller. In

' parallel to the rolls in hinge or bearing ractice these spindles are rotated positively y any suitable mechanism as by sprockets the casing end,-

The guide comprises a smooth rounded bar 6 having an arm 7 near eachend longitudinally adjustable in tubularsockets -8, set screws 9 with hand burs or butterfly heads 10 clamping the-parts in adjustedposition. The sockets are secured in the parallel outbent ends 11 of a rod 12 rotatable I igure 1 is aview in perspective of the roll case ofa' pianola or and chain indicated by the dotted lines at in raised position indicated by the dotted lines, when it isdesired to remove or replace the record roll, 'Otherwise it rests on v the record strip lfijust before it comes into the record roll when being removed, its

weight causing it to smooth out any narrow strips between elongated sound holes or slots, and likewise to prevent the paper overrunning, which otherwise would occur owingto the positive drive connections of the feed and rewinding rolls, wlnch rotate them at constant speed ratio while the varying diameters of the rolls as the record is, shifted from one to the other, cause the record strip to oftentimes buckle up, whenf the teed roll is larger than the rewinding =roll. This is prevented by the guide which retards the paper and keeps an even tension on it. Obviously, a spring or weight with means to adjust it may be used to vary the tension.

-As indicated in Fig. 3, the bearing brackets may consist of a base 16, adapted to befastenedto the casing 1 permanently,

with a hinge late 17 longitudinally ad ustable in paral el guide flanges -18-ther ein,a clamping thumb-screw 1 9 binding it in adjusted position in axial ahnement' with the rolls' I a The device is simpleand is readily applied to anyinstrument. Its details of construc-- ,tion may be varied without departing from the spirit of the invention and I do .not limit myself to any: particular form or arrangement ofparts; v .WhatiI claim as my invention is 2-- 1. The combination of the record winding rolls, tracker boardandcasing therefor of a-self playing piano or the like with a pair offalinedbearings bra'ckets secured to the casing parallel to the rolls, "a pivot rod journaled therein having outturned parallel;

ends, and a presser bar 'adjustably secured to the rod-ends adapted to ride on a record strip passing'from, roll to roll over the traction board, i v 2. The combination of the record winding rolls, tracker board and easing therefor of a.

self-playing piano or the like with a pair oi alined bearing brackets secured to the casin parallel to the rolls, a pivot rod gournale racketslii suitably fastened to the casingl therein having outturned parallel ends, a

above the roll spindles 5. Thumb screws llin the hinges maybe used to clamp the bar pipsser bar, and parallel arms'thereon' ad-' justable longitudinally on the rod ends saidbar being adapted to ride on a record strip passing from roll. to roll over the tracker lit board.

3. The combination of the record Winding rolls tracker board and casing therefor of a self-playing piano or the like With a pair of alined bearing brackets secured to the casing parallel to the rolls, a pivot rod journaled therein having outturned parallel ends,.a presser bar, parallel arms thereon adjustable longitudinally. on the rod ends, said bar being'adapted to ride on a record strip passing from roll to roll over the tracker board, and thumb screws in the brackets adapted to clamp the rod rigidly in the brackets. v

4. The combination of the record'winding rollsytracker board and easing therefor of a self playing piano or the like with a pair of bearing brackets consisting of bases secured to the casing and hinge plates adjustably secured thereon, a pivot rod journaled therein having outtnrned parallel ends, and

a presser bar adjustably secured to the rod ends adapted to ride on a record strip passing from roll to roll.

5. The combination of the record Winding rolls, tracker board and casing therefor of a self playing piano or they like with a pair of bearing'brackets consisting of bases secured to the casing and hinge plates adjustably secured thereon, a pivot rod j ournaled therein having outturned parallel ends, a

presser bar, parallel arms thereon adjustable longitudinally on the rod ends, said bar being adapted to ride on a record strip passing from roll to roll over the tracker board, and thumb screws in the brackets,
